The U.S. Centers for Disease Control and Prevention lifted a moratorium yesterday on transfers of inactivated materials from its clinical tuberculosis laboratory. A bioterror-lab incident last month that might have exposed workers to live anthrax had prompted the halt of transfers from other high-containment labs.

The tuberculosis lab, which last year processed more than 500 specimens, is the first of the CDC’s high-containment labs to be cleared to resume transfers of biological materials. The CDC said its other such labs remain on hold.

The tuberculosis lab was not among those involved in recent incidents. Those labs — one for detecting bioterror agents and another that researches influenza — remain closed. No one appears to have been exposed or become ill as a result of the incidents.
